Tire choice is definitely a big thing and it could probably change a variety of times that we see it out on the tracks. There's that and they don't really put just anyone behind the seat of these things and say "go drive it around the ring"

With how increasingly complicated a car's ECU is getting, slight tweaks and copious amounts of track testing are needed and the E-Pace is no different.

There's a lot of testing in virtual setups and simulations since its often easier to replicate scenarios than to find them for a lot of car makers. With todays technology that has gotten even more intense than ever before. Track testing is just a fraction of all testing.

I agree for sure. Track testing is merely one portion, and a small portion at that, of what vehicles endure in order to get ironed out and figured out. Cars are left running on the dyno for long periods of time. They're put through various simulations. There are way too many tests that we wouldn't be able to list.
